Application fi1ed..April 14, 1928. VSerial No. 270,051'.

'may be re'versed in'the channel; and to provide an improved form ofy sheet metal wall tie which is particularly adapted for use in securing a stone facing to a Concrete wall.,

-An illustrative ernbodiment of -this invention is shown in the aecom'panying draWing,

wherein: I

Figure 1 is a horizontal section of part of a building construction including anV improved wall tie.v V

jFig. 2v is a similar viewv but showing the key in an invertedposition.

F 3 is a fragmentary perspective of lthe channel. p

Fig. 4 is-V an enlarged -section taken on the line 4.-4 of Fig. 2. Fig. is a horizontal section of a Vcolumn mold, showing .two of the'channel members securedto the front sectioI-rbeforeV the concrete is poured; i f The -improved wall ties, to which this in vention is. applied, are adapted for use in securing a masonry facing to many different types of walls. 'Inrthe specific,I construction heroin shown7 the wall vtie is used for secur- 'ing a stone veneer or' facing to aL Concrete ett) column. The tie includes an' improved form of .key having one end anchored in the facing unit, and having its other 'end .interllooked with an improved channel formed in the adjacent structural unit. i

' In the form shown, the improved tie is used for sccuring an 'inner wall 1 to an outer vfacingr of stone 2 bonded with mortar. v

The wall 1 comprises a plurality of vertical columns of concretefpoured into temporary wooden molds 3 built tural shapes 4. v

The concrete columns usually extend from the ground to the top of the building and the stone faeings are generally spaceda short distance from the adjacentcolumns.

In the construction illustrated, the improved wall tie eomprises a channel'member around strue- I 5, which is adapted to be embedded in the Concrete, and .a plurality ofV adjustable keys 6. The Channels 5 and keys 6 are prcferably sheet metal starnpings.

' -The channel member comprises a pair of side walls 7 and 8 and a rear wall 9. The side'walls are corrugated and are arranged to provide a ridge 10 and depression 11 at one side of the channel and a complementary de- .pres'sion 12 and ri'dge 13 on the opposite side. The walls 7 and 8 are arranged so that ad]I ay.cent portions thereof are'substantially par allel, whereby the' channel has 'a uniform width throughout its depth. I

The; outer extremities of the side walls7 and 8 are bent outwardly to form flanges 14 which'are adapted .to bear against the front section of the mold 3 during the pouring of the Concrete. VVhen the column isfinished, the outer faces of theflanges 14. are fiush with the front face of the column.

Formed in the rear wall '9 of the channel member, is a plurality of apertures 15 for. receiving nails 16 which are driven-through the channel for securing it to the front section of the mold. Thesenails remain in the channelafter the mold has beenstripped from the column, as shown in Figs. 1 and 2. I Located between the flanges 14, is an opening 17 extending'longitudinally' of the channel member for receiving the keys 6.

In theform shown, each of the keys 6 comprises a metal strap having .a shank 18 and a head 19. V

The shank 18is corrugated and also flared so. as to provide a broad hearing whichis adapted to'lie between two layers of stone.

The outerr end of theV shank 18 is bent down- I f channel, as shown in Fig. 2.- vWhen the key is reversed, the inner extremity of the head 19 extends only to the ridge 10-and depression 12 instead of to the rear wall 9.

In operation, the channel members 6 are' arranged on end andl nailed to' the front sections of the molds; After the concrete has in the outer facing.

been poured and has properly set, the molds are stripped from 'the columns'and the vertical channel members'left embedded in the concrete, with the openings 17 located in 'the front face of the Wall. The stone facing is then built in front of the column 1. Atcertain vertical intervals, the keys 6 are in-I serted into the Channels and their shanks 18 embedded in the stone. The tie heads 19 are slidable in the channel members so as to permit the shanks 18 to be inserted at any level In the event that the vsh'oulders 20 have been bent upwardly, instead of downwardly, on some of the keys, these keys may be reversed in the Channels as shown in Fig. 2.

This improved construction also permits 'the keys to be attached to the channels When tion to provide a ridge and a depression in one Wall thereof and a complementary depression and ridge in the opposite wall thereof, and a key having one end seated in said channel and substantially conforming to its cross section and having its other end anchored in said.

other unit, said key being reversible in said channel. i i

2. A-wall tie comprising a channel member corrugated in cross section to provide a ridge and adepression in one wall thereof and a complementary depression and ridge' in the opposite Wallthereof, and a key. having one end seated in said channel and reversible therein When partly vWithdrawn therefrom.

3. A walltie-comprising a channel member having a longitudinally extending opening in one vside thereof, said channel being corrugated in cross'section to provide a ridge and a depression in one wall thereof and a complementary depression and ridge in the opposite wall thereof, and a key slidable in said opening, one end of said key being located in said channel and substantially conforming to its cross section, said key being reversible' When partly Withdrawn fromL said channel.

4. A wall tie comprising a channel member corrugated in cross section to provide a ridgeand a depression in one Wall thereof and a complementary depression and ridge in the opposite wall thereof, said channel being uniform in width throughout its depth, and a key having one end seated in said channel, said key conforming to the cross-section of said channel so as to be reversible therein when partly Withdrawn therefrom.

5. Awall tie comprising a channel-member corrugated in cross section, to provide a ridge and' a depression in one Wall thereof and a complementary depression and ridge in the opposite wall thereof, and a key having one end seatedin said channel and conforming to its cross section, said key being reversible when partly withdrawn from said channel.

6. A Wall tie comprising a channel member adapted to be secured to a structural unit, said member Ibeing corrugated in cross section to V nel member having a longitudinally -extend-- ing opening in one side thereof, a key slidable in said opening, one end of said key being located in said channel and substantially con- -forming to its cross section, said key being retudinally extending opening in one side there-l of, said channel being substantially Vuniform in width throughout its depth, a sheet metal key slidable in said opening,'one end of said key being located insaid channel and substan! tially conforming to its cross section, said key being reversiblewhen partly withdrawn from said channel, and a shoulder adjacent the other end of said key adapted to be embedded in another unit. i
